DESCRIPTION OF EMBODIMENT

In an embodiment of the present invention, a printer maintenance guide device and a printer maintenance guide method are realized which are designed to display a whole process of a maintenance guide at once by moving images and enable even a novice or an unfamiliar person to perform a necessary maintenance work and be guided to reliably perform the work at ease after grasping the whole maintenance guide.

A printer maintenance guide device and a printer maintenance guide method according to the embodiment of the present invention are described below on the basis of FIGS. 1 to 6D.

FIG. 1 is a perspective view of a printer (e.g. thermal transfer label printer 1) by an arbitrary printing method and FIG. 2 is a schematic side view of the thermal transfer label printer 1. The thermal transfer label printer 1 includes a printer main body 2, a print paper sheet feed unit 4 for print paper sheet (label continuous body 3), a detection unit 5, a printing unit 6, an operation unit 7, a display unit 8, a power switch 9 and a control unit 10.

The printer main body 2 includes an opening/closing cover 12 which can be opened and closed about a cover opening/closing shaft 11, and a work of mounting the label continuous body 3 or a thermal transfer ink ribbon (described later) and a maintenance work to be described later can be performed in the thermal transfer label printer 1 as shown in FIG. 2 by opening the opening/closing cover 12.

Also, the printed label continuous body 3 is ejected from a label issuance opening 13 between the printer main body 2 and the opening/closing cover 12.

The label continuous body 3 is a label of an arbitrary form such as a label with a liner sheet or a linerless label, and is rotatably mounted on a holding shaft 14 of the print paper sheet feed unit 4 in a state rolled on a support tube 3A. A tag not coated with an adhesive layer or the like may be adopted as the print paper sheet.

The strip-like label continuous body 3 can be fed in a direction toward the detection unit 5 and the printing unit 6 via a guide roller 16 on a transfer path 15 from the print paper sheet feed unit 4.

The detection unit 5 includes a position detection sensor 17 and can detect a relative positional relationship of the label continuous body 3 with the printing unit 6 by detecting a position detection mark (not shown) printed in advance, for example, on the underside of the label continuous body 3.

The printing unit 6 includes a thermal head 18, a platen roller 19 and a ribbon supply shaft 21 and a ribbon roll-up shaft 22 for a thermal transfer ink ribbon 20.

The label continuous body 3 and the thermal transfer ink ribbon 20 are overlapped and nipped at a predetermined printing pressure between the thermal head 18 and the platen roller 19, predetermined information can be printed on the label continuous body 3 by rotating and driving the platen roller 19 and supplying print data to the thermal head 18, and the label continuous body 3 and the thermal transfer ink ribbon 20 eject the printed label continuous body 3 from the label issuance opening 13.

Further, the thermal head 18 is openable and closable with respect to the platen roller 19 by being rotated about a head opening/closing shaft 23 thereof, thereby enabling the label continuous body 3 and the thermal transfer ink ribbon 20 to be mounted between the thermal head 18 and the platen roller 19.

Also, a cutting unit (not shown) including a cutter may be provided downstream of the printing unit 6 or the label issuance opening 13 according to need or an RFID antenna unit (not shown) may also be mounted at a predetermined position of the transfer path 15.

FIG. 3 is a diagram of the operation unit 7 and the display unit 8 provided on one side surface of the printer main body 2.

The operation unit 7 includes a pair of left and right function keys 24, a cancel key 25, navigation keys 26, a play/pause key 27 and an enter key 28.

The function key 24 can switch its function according to an operation mode of the thermal transfer label printer 1.

The cancel key 25 returns a display on the display unit 8 to one previous screen.

The navigation keys 26 include two pairs of upper and lower, right and left arrow keys, i.e. an up-direction arrow key 26A, a down-direction arrow key 26B, a right-direction arrow key 26C and a left-direction arrow key 26D.

The play/pause key 27 functions as an online/offline changeover button and a guide stop button capable of pausing and resuming moving images to be described later.

The enter key 28 is a button for determining a selected content.

The display unit 8 includes a liquid crystal display 29 and a light emitting diode 30 is mounted at a position above the liquid crystal display.

The liquid crystal display 29 can display various contents necessary to operate the thermal transfer label printer 1 and its printing unit 6 and can successively and continuously display a whole process of a maintenance guide for a maintenance work of solving an error from start to end at once by moving images (arbitrary moving images such as photographed images including video images and animation) particularly when this error occurs in the operation of the thermal transfer label printer 1. Further, the liquid crystal display 29 can display a maintenance guide corresponding to a selected one of various maintenance operations of the thermal transfer label printer 1 regardless of the occurrence of an error.

The light emitting diode 30 is lighted when the power switch 9 is turned on and performs light emission processings corresponding to various operations.

Also, a human sensor 31 is mounted at an arbitrary position such as the vicinity of the display unit 8 of the printer main body 2 so that an operator near or before the thermal transfer label printer 1 (display unit 8) can be sensed.

FIG. 4 is a block diagram of the control unit 10 of the thermal transfer label printer 1. The control unit 10 includes a CPU 32, a ROM 33, a RAM 34, an interface 35, a moving image memory 36, a head controller 37, a platen roller controller 38, a position detection sensor controller 39, an operation controller 40, a display controller 41 and a human sensor controller 42.

An arbitrary personal computer 43 is connected to the interface 35, and the thermal transfer label printer 1 can be controlled according to need. Needless to say, the thermal transfer label printer 1 can also independently operate.

A maintenance guide device 44 is configured by the control unit 10, the operation unit 7 and the display unit 8 described above.

In the thermal transfer label printer 1 and the maintenance guide device 44 thus configured, a whole process of a maintenance guide can be successively and continuously displayed from start to end thereof at once on the display unit 8 (liquid crystal display 29) by moving images by the maintenance guide device 44 for various maintenance operations necessary for the thermal transfer label printer 1 when an error occurs in the operation of the thermal transfer label printer 1 or even if no error has occurred.

Specifically, FIG. 5 is a flow chart of a maintenance guide method by the maintenance guide device 44. In Step S1, it is judged whether or not any error has occurred in the thermal transfer label printer 1.

Contents of the error include the exhaustion of the label continuous body 3 and the thermal transfer ink ribbon 20, a paper sheet jam, a ribbon jam and the like as described above. The following description is given, taking as an example a case where the label continuous body 3 has been exhausted.

When an error occurs, a display type is specified in Step S2.

Specifically, the exhaustion of the label continuous body 3 is specified as an error content and the exhaustion of the label continuous body 3 is displayed (i.e. the content of the specified display type is displayed) on the display unit 8 (liquid crystal display 29), thereby presenting it to the operator in Step S3.

In the present embodiment, as a display example of this error content, an error content 29A to the effect that the “label continuous body 3 has been exhausted”, a time 29B with a clock function such as “13:00” and a guide command mark 29C such as by “? mark” as a help icon are displayed with the liquid crystal display 29 divided into a plurality of necessary display areas, for example, as shown in FIG. 3.

The enter key 28 is used in addition to the guide command mark 29C as a guide command button for commanding a maintenance guide for a maintenance work of solving this error.

A plan can be notified to the operator by clearly specifying a required time of the maintenance guide such as “moving images of maintenance guide are displayed for 50 seconds”, for example, in the display area of the time 29B together with a display of the error content 29A.

In Step S4, it is judged whether or not moving images are to be displayed.

Specifically, the operator confirms this guide command mark 29C and requests the display of the moving images by pressing the enter key 28, and the playback of the moving images is started on the basis of this request (Step S5). Also, the operator who needs not view the maintenance guide may perform a predetermined maintenance work without operating the enter key 28.

The whole process of the maintenance guide from start to end can be successively and continuously displayed at once on the display unit 8 (liquid crystal display 29) by moving images by the operation of this guide command button (enter key 28 corresponding to the display of the guide command mark 29C).

Of course, necessary moving images are prepared in the moving image memory 36 according to each error content.

The operator mounts and sets the label continuous body 3 in the thermal transfer label printer 1 (i.e. performs the maintenance work) to solve this error by reference to this maintenance guide by the moving images.

Also, the operator can stop/play back the content of the moving images according to need and confirm the content at his own pace by providing a guide stop button (play/pause key 27) capable of pausing and resuming the moving images.

Further, the moving images can be played back a necessary number of times by providing a guide rewind button (up-direction arrow key 26A) enabling the moving images to be rewound to the start screen. Also, the cancel key 25 may be allotted as the guide rewind button.

Also, instead of providing the operation unit 7 with the play/pause key 27, the cancel key 25, the navigation keys 26, the enter key 28 and the like as mechanical buttons, the guide command button (enter key 28 or guide command mark 29C), the guide stop button (play/pause key 27), the guide rewinding button (cancel key 25 or navigation keys 26) or the like of a touch panel type may be displayed on the liquid crystal display 29 of the display unit 8.

FIGS. 6A to 6D are diagrams showing an example of these moving images as essential screens. FIG. 6A is a schematic side view showing the interior of the printer main body 2 with the opening/closing cover 12 opened. FIG. 6B is a schematic side view showing a process of removing the label continuous body 3 remaining in the printing unit 6 and the support tube 3A of the label continuous body 3 remaining in the print paper sheet feed unit 4 (holding shaft 14) by rotating and opening the thermal head 18 to be separated from the platen roller 19. FIG. 6C is a schematic side view showing a process of holding a new label continuous body 3 on the holding shaft 14 and inserting it between the thermal head 18 and the platen roller 19. FIG. 6D is a schematic side view showing a process of nipping the label continuous body 3 together with the thermal transfer ink ribbon 20 by rotating and closing the thermal head 18 with respect to the platen roller 19.

Specifically, by viewing the moving image represented by FIG. 6A, the operator can confirm that there is no more label continuous body 3 on the holding shaft 14 of the print paper sheet feed unit 4 and a small rear end part of the label continuous body 3 is remaining in the printing unit 6 when the opening/closing cover 12 is opened.

A transfer is made from the moving image of FIG. 6A to that of FIG. 6B and, by viewing the moving image represented by FIG. 6B, the operator can confirm the removal of the remaining label continuous body 3 (see an arrow 3B for supplementary explanation in FIG. 6B) and the removal of the support tube 3A of the label continuous body 3 (see an arrow 3C for supplementary explanation in FIG. 6B) by rotating and opening the thermal head 18 to be separated from the platen roller 19 (see an arrow 18A for supplementary explanation in FIG. 6B).

A transfer is made from the moving image of FIG. 6B to that of FIG. 6C and, by viewing the moving image represented by FIG. 6C, the operator can confirm to set a new label continuous body 3 on the holding shaft 14 and insert the label continuous body 3 between the thermal head 18 and the platen roller 19 via the guide roller 16 (see an arrow 3D for supplementary explanation in FIG. 6C).

A transfer is made from the moving image of FIG. 6C to that of FIG. 6D and, by viewing the moving image represented by FIG. 6D, the operator can confirm to nip the label continuous body 3 together with the thermal transfer ink ribbon 20 by rotating and closing the thermal head 18 with respect to the platen roller 19 (see an arrow 18B for supplementary explanation in FIG. 6D).

Also, the moving images are so created that the operator can reliably see and confirm essential guide parts by enabling the essential guide parts which are essential parts of the maintenance guide, e.g. each of the scenes displayed in FIGS. 6A to 6D, to be displayed in a still state for a predetermined set time so as not be overlooked.

Alternatively, it is also possible to discontinuously display only each essential guide part (e.g. only essential guide parts shown in FIGS. 6A to 6D) by operating the right-direction arrow key 26C and the left-direction arrow key 26D on the basis of the operator's intention.

Further, the human sensor 31 is provided near the display unit 8 and it is possible to pause the moving images when this human sensor 31 senses no operator near the display unit 8 and control to automatically resume the moving images from the stopped image when the human sensor 31 senses the operator again.

Also, in the present embodiment, a mounting angle of the display unit 8 (liquid crystal display 29) with respect to the printer main body 2 can be switched between a mounting surface for the display unit 8 and the operation unit 7 and a surface substantially at a right-angle position particularly as shown by a virtual line in FIGS. 1 and 2. The maintenance work can be easily performed while the moving images are viewed as described above by making an angle of viewing the interior of the printer main body 2 (posture of the operator) and an angle of viewing the liquid crystal display 29 (posture of the operator) substantially equal.

Specifically, the display unit 8 (liquid crystal display 29) can be arranged on a surface identical or equivalent to the surface where the interior of the printer main body 2 can be looked over so that the maintenance work can be performed in the printer main body 2 while the moving images of the maintenance guide are viewed.

Further, the display unit 8 (liquid crystal display 29) enables the operator to perform the maintenance work in the printer main body 2 in an arbitrary posture easy to view the liquid crystal display 29 by being made detachably attachable to the printer main body 2 and in a state where wired or wireless data communication with the control unit 10 of the printer main body 2 is possible.

Furthermore, in the present embodiment, an audio guide corresponding to the maintenance guide can be provided by an arbitrary technique together with the moving images as described above.

Further, a language guide corresponding to the maintenance guide can be displayed together with the moving images on the liquid crystal display 29. This language guide can be prepared integrally to or separately from the moving images and the language guide of each language can be prepared.

In Step S6 following the playback of the moving images in Step S5, it is judged whether or not the error has been solved. A return is made to Step S1 unless the error has been solved, whereas a standby screen is displayed in Step S7 to indicate that the thermal transfer label printer 1 is in a state capable of the next printing operation when the error has been solved.

Also, a control to transfer to Step S7 is possible by the operator pressing a predetermined button (e.g. play/pause key 27) after performing a series of maintenance processings including those of FIGS. 6A to 6D.

When no error has occurred in the thermal transfer label printer 1 in Step S1, it is judged in Step S8 whether or not to perform printing by the thermal transfer label printer 1. When printing is to be performed, a print layout and print data are obtained and printing is performed in Step S9 and a still image of the print layout being currently printed is displayed in Step S10.

Unless printing is to be performed in Step S8, it is judged in Step S11 whether or not an information screen is on display.

Here, the information screen is a screen enabling the operator to arbitrarily select a predetermined function or processing from a menu screen displayed on the liquid crystal display 29 of the display unit 8 by a tree structure. Since this information screen is displayed in a mode different from the one in which the error content 29A and the guide command mark 29C of the liquid crystal display 29 are displayed, an access can be made by selecting an information mark 29D such as by an “i mark” as shown by a virtual line in FIG. 3 by means of the enter key 28 or the like.

Unless this information screen is selected, an exit is made from this series of processings.

The display of the information screen is selected and it is judged in Step S12 whether or not the operator is requesting a guidance screen in the information screen. When it is requested, a transfer is made to Step S2 to specify the display type and the processings in Step S3 and subsequent Steps described above are performed.

Here, the guidance screen is a screen including maintenance guides in the event of errors and listing up the maintenance guides for a maintenance work of performing various maintenance operations of the thermal transfer label printer 1, and displayed on the liquid crystal display 29 similarly to the information screen, and the operator can select or instruct an arbitrary maintenance guide by means of the navigation keys 26 and the enter key 28 (guide command button).

Specifically, in the maintenance guide device 44 according to the present embodiment, the moving images displayed on the display unit 8 can show the maintenance guides for the maintenance work of performing various maintenance operations of the thermal transfer label printer 1, including the maintenance guides in the event of errors.

The various maintenance operations include general operations such as an exchanging work and a cleaning work of the position detection sensor 17, the thermal head 18 and the platen roller 19 and, further, the cutting unit and an RFID antenna provided according to need, and various button operations, let alone the mounting of the label continuous body 3 and the thermal transfer ink ribbon 20 into the thermal transfer label printer 1 described above.

When the cleaning work of the thermal head 18 is, for example, selected and requested by operating the navigation keys 26, the enter key 28 and the like on the above guidance screen, a thermal head cleaning work is specified as the display type (Step S2) and moving images of that maintenance work (cleaning work) are continuously displayed on the liquid crystal display 29 (Step S5).

Also, in the case of transfer from Step S12 to Step S4 and Step S5, the above navigation keys 26 and enter key 28 can be used as the guide command buttons used by the operator. Assuming that the display of the moving images is already commanded in Step S12, a control can be executed to automatically transfer from Step S4 to Step S5. Of course, in the case of transfer from Step S12 to Step S4 and Step S5, it is also possible to control to command the display of the moving images anew using the guide command mark 29C such as by the “? mark” and the enter key 28 as the guide command buttons as in the case of commanding a maintenance guide in the event of an error to transfer from Step S1 to Steps S4 and S5.

Accordingly, the operator can select the maintenance guide of the maintenance work he desires to confirm and improve a skill in the operation of the thermal transfer label printer 1 by viewing the whole moving images even if an unpredictable error occurs during a print issuing operation of the thermal transfer label printer 1.

In this way, the whole process of the maintenance guide from start to end is successively and continuously displayed at once on the display unit 8 by the moving images by the operation of the guide command button (navigation keys 26, guide command mark 29C, enter key 28, etc.) provided to command the maintenance guide for the maintenance work when an error occurs in the operation of the thermal transfer label printer 1 or even if no error occurs. Thus, even an operator unfamiliar with various maintenance works can reliably perform the maintenance work at ease after grasping the whole process of the maintenance guide.
